Is there a way to download all the tips and notes?
I mostly study on mobile. I didn't even know the tips and notes section existed until I happened to open a new lesson in the browser today (something I almost never do).
Is there a way I can download all the tips and notes so I can view them on mobile?
They're available here: http://duonotes.wikia.com/wiki/Esperanto
If you've not yet joined, the Duolingo Esperanto Learners group on Facebook is a great resource - tons of learning materials, and experts available to answer your questions...
